The Carbon Border Adjustment Mechanism entered its definitive phase on January 1, 2026. For EU procurement teams, this is no longer a compliance planning exercise — it is an active cost variable sitting inside every sourced category that crosses a non-EU border.
Under the definitive regime, EU importers must purchase CBAM certificates corresponding to the verified carbon content of imported goods. The covered categories are steel and iron, aluminium, cement, fertilizers, hydrogen, and electricity. The first quarterly financial declarations covering January–March 2026 are triggering in Q2 2026, and penalties for non-compliance or underreporting are material.
The direct procurement impact depends on origin. Steel from Ukraine or Turkey carries significantly different embedded carbon intensities than steel from South Korea or India. The same category purchased from different suppliers can generate certificate obligations that vary by 40–60% depending on the production route. For buyers still operating on fixed-price annual contracts with non-EU steel, aluminium, or cement suppliers, CBAM certificate costs are not passed through automatically — they land on the importer unless the contract explicitly allocates them to the seller.
What procurement teams should do now: first, map every active supply contract where the seller is outside the EU and the goods fall under one of the six CBAM categories. Second, obtain verified carbon content data (CBAM embedded emissions reports) from each affected supplier — this is the basis for certificate calculation, and suppliers who cannot provide this data create audit and penalty risk. Third, review contract structures: any fixed-price contract running through 2026 and 2027 that does not include a CBAM pass-through clause is an exposure that needs to be addressed at the next renewal.
The EU ETS carbon price recovered to €73–75 per tonne in June 2026 after a Q1 trough. That price feeds directly into CBAM certificate costs. A tonne of hot-rolled coil from a typical non-EU mill carries embedded carbon of 1.6–2.2 tonnes of CO₂ equivalent — meaning €120–165 in CBAM cost per tonne of imported steel at current ETS prices. At scale, this is a category-level cost shift, not a rounding error.
Procurement teams who have not yet started the supplier data collection process are behind. Certificate calculations require verified emissions data — estimated or default values trigger higher certificate quantities and create regulatory risk.
